Transcription

1 Overview HP guard for Linux x86 is high availability clustering software designed to protect applications and services from planned and unplanned downtime. guard for Linux ensures 24x7 application availability by packaging an application or service with its associated resources, and moving that package to other servers as needed. Packages can be moved automatically when guard detects a failure in a resource, or manually in order to perform system maintenance or upgrades. By monitoring the health of each server (node) within a cluster, guard for Linux quickly responds to failures such as those that affect processes, memory, LAN media and adapters, disk, operating environments, and more. guard for Linux also includes many out-of-the-box features that ensure scalability and allow intricate control over cluster configuration, and optimizes in-house expertise for businesses already running guard for HP-UX. Application Integration Toolkits are also available, and serve to quickly integrate complex applications into a guard for Linux cluster. The Application Integration Toolkit portfolio includes the guard Toolkit for NFS and the guard Contributed Toolkit Suite which are available at no charge. In addition to high availability within a data center, the guard Solutions for Linux offers a powerful and comprehensive suite of disaster recovery solutions. The following is a quick summary of HP guard for Linux features and support.

SADTA provides: Error free assignment of a role such as primary or secondary to a site Allow the tolerable failures at a site level c DA Worldwide Version 43 August 17, 2015 Page 7

8 Product Highlights Architecture (SADTA) Automatic role transition of active state to a surviving site when primary site does not meet the minimum required criteria to assume the active status Increase overall cluster availability with fault resilient ProLiant HP ProLiant quality and innovations provide maximum redundancy and fault-resilience across processor, disk, memory, power, cooling and I/O subsystems. Configurations of HP guard for Linux are completely tested and qualified on HP servers across multiple applications. Improved application environment failover with support of virtualization technologies HP guard for Linux supports key virtual machine offerings on ProLiant server platforms to ensure the utmost availability and flexibility for application environments. Greater protection over typical failover cluster configurations HP guard for Linux uses additional hardware paths and software techniques to keep the application running on the same node and failing over to a new node as a last resort. Ensure data integrity by eliminating "splitbrain syndrome" Cluster arbitration is essential to ensure the highest level of availability and data integrity. HP offers two alternatives for this requirement, one of which is required for a 2-node configuration and recommended for 3- or 4-node configurations to cover multiple failures. One method is through cluster lock LUN, which utilizes a shared LUN to provide a tie-break (arbitration) mechanism in the event a failure causes a 50% split in the cluster. The other method is through a Quorum, which runs on a separate PC or server and can arbitrate up to 50 clusters/100 cluster nodes. A single Quorum can provide arbitration service to both Linux and HP-UX clusters. This is particularly valuable in split-site configurations, with the Quorum at a third site, to ensure a cluster can create quorum in the event of a site failure. Quorum identifies the previous Active site where the workload is running, and prioritizes the Quorumgrant to be given to the original Primary site, thus preventing the expensive and unnecessary failover of the complex workload. Perform online reconfigurations Reconfigure cluster nodes and packages and optimize your cluster performance without taking down the cluster. Eliminate downtime for guard software upgrade using Live Application Detach Use Live Application Detach (LAD) to do maintenance of the guard cluster infrastructure (including the heartbeat network) with near zero downtime Cluster Verification Verify whether packages in the cluster are able to fail over and the cluster is configured correctly with a single, easy-to-use command that can also be automated to further reduce unplanned failures due to human errors Reduce downtime for application software or OS upgrade using Allows software and hardware upgrades while the cluster remains up and running. c DA Worldwide Version 43 August 17, 2015 Page 8

11 Technical Specifications HP guard for Linux Supported Configurations NOTE: This is a list of supported configurations at time of writing. Please refer to the guard for Linux Certification Matrix at for the most up-to-date list of supported configurations and important notes and caveats. Memory requirements guard requires approximately 15.5 MB of lockable memory. Cluster arbitration requirements Cluster arbitration is essential to ensure the highest level of availability and data integrity. HP offers two alternatives for this requirement, one of which is required for a 2-node configuration and recommended for 3- or 4-node configurations to cover multiple failures. Cluster Lock LUN - Utilizes a shared LUN to provide a tie-break (arbitration) mechanism in the event a failure causes a 50% split in the cluster. Cluster Lock LUN requires a dedicated LUN with a minimum size of 100K. Quorum : Runs on a separate PC or server and can arbitrate up to 150 clusters/300 cluster nodes. One Quorum provides arbitration service to Linux and HP-UX clusters. This is particularly valuable in split-site configurations, with the Quorum at a third site, to ensure a cluster can create quorum in the event of a site failure. The node on which the Quorum is running must have network connectivity to the clusters for which it is providing services. Ensure that the connection with each node is independent of the cluster heartbeat connection so that both are not likely to fail at the same time. The Quorum in a Linux environment can manage up to 150 clusters and 300 nodes. The Quorum and clustered nodes may be on different subnets. You can create the Quorum to be a package, so it is highly available. The package must run outside the cluster that the quorum server serves. Run on any HP PC or server certified for SUSE 11 or Red Hat EL 5 or above. Minimum memory requirements 128 MB Locks up to 16 MB of memory Single quorum service for a maximum of 300 nodes; up to 150 heterogeneous clusters Cluster Types Active/Active Active/Standby Rotating Standby Linux Distributions Red Hat Enterprise Linux 7 (includes AP) Kernel Versions Red Hat Enterprise Linux 6 (includes AP) Kernel Versions Red Hat Enterprise Linux 5 (includes AP) Kernel Versions SUSE Linux Enterprise Server 12 SUSE Linux Enterprise Server 11 Hypervisors VMware ESX and ESXi 5 and 6 Red Hat Enterprise Linux (RHEL) 6 - Kernel-based Virtual Machine (KVM) HP ProLiant Servers Fibre Channel Storage HP ProLiant Gen9, Gen8 and G7 Rack Mount (DL), Tower (ML) and BladeSystem (BL) servers HP Storage 3PAR Utility Storage Family o F-Class Storage Systems o T-Class Storage Systems o StoreServ arrays c DA Worldwide Version 43 August 17, 2015 Page 11

17 Technical Specifications HP guard Audit (HP-UX and Linux) HP guard Audit is ideal for assuring optimal configuration of current guard Metrocluster environment HA332A1 Cluster Topologies Fibre Channel configuration topology Up to 32 nodes on a Fibre Channel configuration A quorum service or cluster lock LUN is only required for 2-node configurations, it is optional for 3- to 4-node configurations. LAN connection to switches, white papers are available on the Technical documentation section of the HP Networking web site describing how to set up the LAN environment for the best availability. The key items that need to be in the servers are the correct number and type of LAN connections and the Fibre Channel host bus adapters (HBAs). In a Fibre Channel storage system, the host port interconnects act as an internal switch to provide data-path redundancy. The below diagrams show a dual-controller Fibre Channel system in a switch attach configuration in which host port interconnects are typically enabled in order to provide fault tolerance. When the host port interconnects are enabled, port 0 on each controller is cross-connected to port1 on the other controller. This provides redundancy in the event of failover by making volumes owned by either controller accessible from either controller. Please refer to 3PAR documentation for complete connectivity details. c DA Worldwide Version 43 August 17, 2015 Page 17
